Methods and systems for performing laser-assisted surgery on an eye form a layer of bubbles in the Bergers space of the eye to increase separation between the posterior portion of the lens capsule of the eye and the anterior hyaloid surface of the eye. A laser is used to form the layer of bubbles in the Bergers space. The increased separation between the posterior portion of the lens capsule and the anterior hyaloid surface can be used to facilitate subsequent incision of the posterior portion of the lens capsule with decreased risk of compromising the anterior hyaloid surface. For example, the layer of bubbles can be formed prior to performing a capsulotomy on the posterior portion of the lens capsule.
